Sintered Pleated Filter Cylinder - High Performance Filtration from China Suppliers and Factory

Introducing the Sintered Pleated Filter Cylinder, a high-performance filtration solution from leading China suppliers and manufacturers. Crafted with a multi-layer structure, this filter element utilizes premium stainless steel fiber sintered felt or woven mesh as its base material, processed through an innovative folding wave technique. Available in various core materials, including 304, 316L, and iron chromium aluminum fiber, our filters boast exceptional porosity, outstanding dirt-holding capacity, and remarkable resistance to high temperatures and corrosion, The filter element is meticulously sealed using advanced argon arc welding and other methods, ensuring durability and reliability. The unique folded design significantly enhances the filtration area, offering 3-5 times the capacity compared to traditional filters, making it ideal for high-precision and high-pressure applications in complex working conditions. Trust in our factory for cutting-edge filtration solutions that meet your demanding requirements

Production process of our Sintered Pleated Filter Cylinder

Raw material processing

screening stainless steel powder or fiber mat, mixing additives to enhance sintering performance.

Molding process

Folding process: fold metal mats or woven mesh into corrugated shape to increase the surface area.

Press molding: the mold presses the powder into a hollow cylindrical embryo under high pressure.

High-temperature sintering

Sintering at about 1500℃ under vacuum environment to form a stable porous structure.

Post-treatment

Cutting, welding end caps (argon arc welding to ensure sealing), surface polishing and anti-rust treatment.

Advantages of our Sintered Pleated Filter Cylinder

1. High-efficiency filtration

The folded structure increases the dirt-holding capacity by more than 50%, suitable for highly viscous liquids and gases.

2. Strong durability

Acid and alkali resistance, organic solvent corrosion, no deformation under high pressure difference (pressure up to 6.9MPa).

3. Easy maintenance

Support backwashing, chemical cleaning (such as 0.1N NaOH or citric acid) and ultrasonic regeneration, reuse rate up to 90%.

4. Economical

Long-life design reduces the replacement frequency, and the comprehensive cost is lower than the disposable cartridge.

5. Environmental protection and safety

All stainless steel material without fiber shedding, in line with the food, pharmaceutical industry health standards.

Application of our Sintered Pleated Filter Cylinder

Frequently Asked Questions

What materials are Sintered Pleated Filter Cylinders made of?

Our filter cylinders are made of high-quality materials including 304 and 316L stainless steel, duplex steel, and Hastelloy, offering excellent corrosion and high temperature resistance.

What is the advantage of a pleated structure over a standard cylinder?

The folded or pleated design increases the effective filtration surface area, which improves the overall dirt-holding capacity by more than 50% compared to non-pleated cylinders.

Can these filter cylinders be cleaned and reused?

Yes, they are highly reusable. They support various cleaning methods including backwashing, chemical cleaning (such as 0.1N NaOH or citric acid), and ultrasonic regeneration, with a reuse rate up to 90%.

What temperature and pressure limits can they withstand?

They operate safely within a temperature range of -200℃ to 600℃ (with special materials reaching up to 1000℃) and can withstand working pressures from 0.1 to 30MPa.

Do you support custom sizes and connections?

Yes, we support non-standard customization. We offer diameters from 25-180mm, lengths from 100-1500mm, and interfaces including threaded, 222, 226, flange, and fast card.
